"We wanted to engage with his philosophy by hanging the artwork where people don't have to pay to get in and can experience Banksy's art and join us in a critical debate on developments on the art market."

After 3 March, the artwork will be moved to the Staatsgalerie Stuttgart museum.

The painting's owner - an anonymous European art collector - agreed to go through with the purchase after it was shredded.

It had been estimated to sell for £200,000 to £300,000 before it sold for £1m and some experts believe the shredding increased the value of the artwork.
